With latest toolchain, kernel and userland,
my firefox gets sefgault every run.

The core dump generated from PTHREAD_DIAGASSERT=ae does not show
any useful things.
See:
Core was generated by `firefox'.
Program terminated with signal SIGSEGV, Segmentation fault.

And I cannot get any text output to stdout.
As far as I understand correctly, PTHREAD_DIAGASSERT=e enables the output
to stdout.


Still I feel that pthread_equal() is cause of my segfault.
